Rita: Vlad, can you help me?
Vlad: Yes, sure. What’s the matter, Rita?
Rita: I’m having trouble while trying to create a new document on this computer.
Vlad: I see. There are two options, either you need some updates for your software, or there are some viruses on your computer.
Rita: Viruses! It’s impossible. I have reliable anti-virus software. Should be updates.
Vlad: Let me see. Yes, indeed, you need to update the programme. Other than that, make sure you don’t open unknown documents. It is a frequent way of cyber espionage. I have once received a document within an e-mail saying that it’s from my close friend. I also had anti-virus, but when I opened this document, it caused sensible damage to my personal documents. Some of them were lost.
Rita: How horrible! Did you manage to restore them?
Vlad: Only with the help of a professional programmer.
Rita: It’s amazing how computers have entered people’s lives. We store all important information on them, while that can be really dangerous.
Vlad: That’s true. Every house today has at least one or two computers. Some people use laptops, some use iPads and smartphones. Nearly every modern gadget allows us to connect to the Internet and to share our personal information. We should be careful with online fraud.
Rita: What do you mean by online fraud?
Vlad: I mean, when you enter your bank account, you should be hyper-careful as there are lots of cases of account takeover.
Rita: I see. What complicated inventions are these computers! I wonder who invented them.
Vlad: Well, all I know is that they were invented long before we were even born. The first Z3 computer was invented in 1941 by German engineer Conrad Zuse. I don’t know the exact reason, but perhaps it was invented for some calculations or for storing the information. This computer was soon destroyed by bombing during the war.
Rita: That’s interesting. However, I think that personal computers were introduced much later.
Vlad: You’re right. The idea of personal computers didn’t exist until 1960s. Moreover, home computers were developed for household use in early 1980s. I know that IBM company introduced one of their successful releases in 1981.
Rita: As far as I remember, the first desktop and gaming computers appeared in our country in 1990s, while portable computers, such as laptops, appeared much later.
Vlad: That’s true. Today we have netbooks, tablet PCs, pocket PCs and hundreds of other smart gadgets in the stores.
Rita: Well, I should say that many things have changed since we started using computers.
Vlad: Do you mean positive or negative changes?
Rita: Both. Speaking of positive changes I’d like to mention easy access to any type of information, rapid communication among distant relatives and friends, useful software, which helps people with their jobs.
Vlad: What are the negative points?
Rita: Security gap, of course.
Vlad: Exactly. That’s the main problem.
Rita: I always try to purchase the best anti-virus software to make sure my personal computer is highly protected.
Vlad: Me too. Nevertheless, we need to be alert about various tricks. Sometimes, we intent to share our photos or personal information with friends through social networking. At the same time, some hackers can steal our information and speculate with it.
Rita: I see. So, I better be careful with that. I have several social network accounts where I share my photos with friends.
Vlad: Just don’t accept friendship from strangers and check your safety settings.
Rita: Thanks, Vlad. You gave me food for thought today.
